As previously reported, Pokmon trainers can control the evolution of their Eevee simply by changing the name. Change Eevee’s name to Sparky for a Jolteon, Pyro for a Flareon, and Rainer for a Vaporeon.
Those three are first-generation Pokmon. But what about Espeon and Umbreon?
Espeon and Umbreon are second-generation Pokmon. In preparation for the eventual release of the second generation of “Pokmon Go,” second generation trainers will have to know how to evolve their Eevee into Espeon (psychic-type) and Umbreon (dark-type).
There are rumors saying that if trainers want to evolve their Eevee into Espeon and Umbreon, they will have to do it during daytime and nighttime, respectively. Trainers will also have to do a lot of walking and be in a higher player level.
There are a lot of speculations and theories on how one can evolve their Eevee.
One theory suggests that in order to evolve Eevee into one of the two forms, a trainer will have to feed it a lot of Pokmon candy to make them stronger and increase their combat points (CPs). Once the Eevee’s CP increases to a higher level, the trainer will then have the option to evolve it. Eevee’s evolution, however, will depend on the time of day. If it evolves from 4 a.m. to 5:59 p.m., then it will turn into Espeon. If it evolves from 6 p.m. to 3:59 a.m., then it will turn into Umbreon.
Of course, trainers should know that there are eight evolution paths for Eevee. Besides the first five mentioned, there is still Leafeon, Glaceon, and Sylveon. Leafeon and Glaceon are both fourth-generation Pokmon, while Sylveon is sixth-generation.
It is still not known if the latter three will appear in the second generation of “Pokmon Go” since they are from later generations in the Pokmon games.
For trainers who are having difficulties catching Eevee, try hatching an egg. According to Heavy, 17 percent of all 10-kilometer eggs that were hatched was an Eevee.
